Sony announces 84 inch 4K LED TV

Last week the International Telecommunication Union approved a new 8K television specification which also includes a smaller 4K format. Sony seems to be following the trend of ever-increasing pixels, because today the company unveiled a 84 inch LED TV which features a resolution of 3840 by 2160 pixels, also known as 4K.

The Bravia KD-84X9005 comes with a 50W 10-unit stereo speaker system and passive 3D technology. It's a milestone for the electronics company, because it's Sony's largest TV ever and the company's first passive 3D screen. Of course there's almost no 4K content available today, so that's why Sony included the 4K X-Reality PRO picture engine which upscales all content to use every pixel on the screen. You can also display photos in full resolution on the 8 megapixel screen. The TV also features Smart TV, Wi-Fi and the side speakers are detachable if you want to use your own audio setup.

Sony wants to be one of the first company's to bring 4K to the home. Sony Pictures already shoots its movies in 4K and if you go to the cinema, chances are you are watching a movie projected by a Sony 4K projector as well. According to Kaz Hirai, CEO of Sony, the newest addition to the company's Bravia line-up is "a major step forward":

"It's an unprecedented and revolutionary viewing experience. The experience is so immersive, you want to touch everything in front of you."

European customers will be able to buy the TV for €25,000 ($31,000); U.S. pricing has not been announced yet. The TV will be released before the end of 2012.

I'm glad I dont work for Sony anymore, I was good at sales.. But this one might be a little harder to sale lol.. Amazing im sure, but the cost of them is just to much for now..

We've just started doing 4K content at work and speccing machines to output at 4K. It's surprisingly difficult to test without any TVs like this available. We have to use an X4 unit and split it on to 4 1080 screens.

Getting the machine to do the 4K res is also a pain in the backside.

High Efficiency Video Coding (HEVC) is not finaled yet (January 2013) and they are already releasing those TV's. I mean, I can see this being use in post-prod studios for playback purpose (dailies maybe?!) with 4k-8K image sequences; but for home entertainment?!? Nahhh...
There's no mature video codec ready for these kinds of resolution and will studios, big or small as they might be, re-release or re-scan (if needed) movies in 4k-8k any time soon? This BBC article ( says and I quote : "I suspect that we won't see this become available to consumers below $10,000 until 2025,"
That's a loooong time from now.

for $31k I could build a small home theater with a good DLP projector and 21:9 ratio screen (cinema scope ratio) with a good screen and a DTS sound system with higher end speakers...

Why the sudden shift in how we name the Resolution? We call 1920x1080 "1080p" and we call 1280x720 "720p". Why are we suddenly calling 3840x2160 "4K".

Lets stick with conventional naming and call it "2160p". Or are they thinking because it's a bigger number, people with low IQ's will be impressed?

Additional Note about 4K content availability.

Several movie distributors have been moving over to 4K, and Sony Pictures has
released several 4K movies, so without the upscaling features, there truly is 4K content available to consumers right now.


The screen resolution is not really 4K, as 4K is usually considered 4000+ pixels horizontal, not diagonal as Sony is now trying to implement as it is consistent with the screen size measurement 'scheme'.

I'm sure the display will take a REAL 4096x2160 image, but it is not a native 4K display.

Think of it like the 720p HD Plasma screens that are actually only capable of 1024x768 that is in the HD aspect ratio. They are not truly 1280x720p, and unless you are a gamer or use your computer on the display might not notice it isn't native.

Some MFRs, like Sony, are using the 4K term for sub 4K displays, but even Sony themselves just last year was clear when they released a 4K projector that 4096x2160 was 4K.

Additionally, there have been many true 4K displays around for years now, from Toshiba, Panasonic, LG, etc.

So unless this is 2006, Sony is not going to be the first, nor the cheapest, nor the best. Do some homework on 100" screens from other companies that actually have 4K resolutions.

By the time I have a place to put a TV this big, they'll probably cost $3000.

At that time, just rent/buy a place with a den/bonus room/extra bedroom that you can covert into a real theater, and have a 20-30' screen with a good projector at the $3000 price point.

I've seen it at IFA, it's absolutely amazing. The difference is like a regular iPad vs a Retina iPad. You don't really miss it when it's not there, but when you have the detail it just makes everything four times as awesome.

The passive 3D is brilliant too, it's got completely no ghosting and the glasses are very comfortable to wear, even over your regular glasses.

wasn't the first HD tv commercially available in 1990 for $60K? i think that was also made by sony...if that took about 15 years to become ubiquitous, i suppose it'll take about 10 for this.

I was stupid years ago and dropped 4,000 on a DLP. It was an amazing TV but in hindsight not anywhere near worth 4 grand. Maybe a 1,000... Lesson learned though.

I still think it's misleading to call the specification 4K when the number of pixels is below that (at 3840). Like hard-drive sizes the discrepancy will continue to increase to a point where the difference is laughable. By the time they get up to 128K the actual number of pixels will be less than 123K - a difference of over 5000 pixels.

Misleading name is misleading.

Whatever, all 4K screens will be below 4000 so everyone is on the same page. I guess you're right, they should have called it 3.840K.

It's just a name for a specification, not an actual measurement. Considering how much easier it is to call it 4K, no one will really care anyways.

"You can also display photos in full resolution on the 8 megapixel screen."

Surely not if you have a greater then 8MP camera? Although I admit I would love to see some of my DSLR photos on that screen....

"€25,000 ($31,000)"


Not only is the price range out of the reach for most 'home' users, but at this price it is NOT the first to offer this resolution or size either.

There have been several screens from Panasonic to Toshiba that have offered 4K resolution on larger screens, although they are expensive as well.

Additionally, if a homeowner was 'serious' about TV they could build a rather nice theater with a dedicated 4K projector, even one from Sony, or if they wanted to get clarity and brightness, put together an array of projectors.

Throw together four (or eight) mid range 1920x1080 projectors in a theater room setup or configure them as rear projection in a wall encasing if ambient light is an issue. So even if you shell out $1000-2000 per projector and $200 to array them or a computer to combine the array, it is going to far cheaper than this goofy little TV, look significantly better, and can be a 30' (foot) screen.

Projection is not for everyone, but if you are going to spend this kind of money, you can afford to dedicate a room to be a theater.

I guess their marketing is working though, cause people notice their announcements, but the ones for the Toshiba and Panasonic displays that LITERALLY go back to 2005/2006 are old news or overlooked?

Gotta start somewhere, so it's neat that Sony is pushing the envelope.
Loooong ways to go before this hits mainstream though. We're talking Blu-ray obsolescence.

yeah, but can those projectors do 4k? Speaking of which, why such his resolution, you need perfect 20.20 vision to fully enjoy 1080p, just another gimmick, just like apples retain display
